HARROW.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Replication filed February 26, 1907. Serial No. 359.351.

T o all whom fit may concern:

Be it known that 1, FRANK citizen of the United States, residing at Sterrett, in the county of Ellis and State of Texas,

i shaft 1 and loosely embrace it.

sector 6 which have invented a new and useful Harrow, of which the following is a specification.

This invention relates to harrows of that character designed for collecting stalks after the samehave been cut.

The object of the invention is to provide a riding harrow the teeth of which can be simultaneously swung upward out of engagement with the stalks.

A still further object is to provide means for holding the stalks upon the ground while the teeth are being withdrawn therefrom.

A still further object is to provide means whereby the harrow frame can be bodily' raised out of operative position.

Vith these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

1n the accompanying drawings is shown the preferred form of the invention.

1n said drawings: Figure 1 1s a plan view Iof the harrow; Fig. 2 is a longitudinal section therethrough; and Fig. '3 is a front elevation of one side portion of the harrow.

Referring to the figures by characters of reference, 1 is a rock shaft extending transversely of the machine and loosely connected to this rock shaft is a tongue 2 having diagonal braces 3 which are also mounted on the This shaft has a lever 4 secured to it and provided with a plunger 5 designed to engage a toothed is secured upon the tongue. The drivers seat 7 is also supported by the tongue. The end portions of the shaft 1 are journaled within hangers 8 supported by rotatable axles 9 which are carried by the supporting wheels 10. A gear 11 is secured to each axle 9 and meshes with a gear 12 secured to the shaft 1, and an arm 13 extends from each axle 9 and has chains 14 connected thereto. These chains extend forwardly and rearwardly and are secured to the side rails 15 of the harrow frame. Said side rails are connected by parallel cross bars 16, each of which has an arm 17 extending upward from the central portion thereof, all of said arms being pivotally connectedeby a coupling bar 18. The bars 16 are mounted to rotate within the side strips Hosronn, a l

15 and it is apparent that in view of the connections 17 and 18 all these bars will rock Extending from each of the bars 16 are rearwardly projecting arms 19, each of which is preferably V-shaped and has a tooth 20 secured toit in any desired manner. 1n the drawings each arm, which is made of a heavy rod bent into proper shape, has a casting 21 suitably secured in the apex of the arm and serves as a means for fastening the tooth 20 thereto. These teeth are disposed at desired intervals apart and as they are carried in rear of the bars 16 it is apparent that when the arms are rocked in one direction all the teeth will be swung upward away from any ma-l terial which may be engaged thereby.

1n order that the arms 16 may be manually actuated whenever it is desired one or more arms 22 are secured to one of the bars 16 and each of these arms is connected by means o a rod 23 to an arm 24 secured to the shaft 1. These arms 24 preferably extend rearwardly from the shaft 1 and another series of arms 25 extends forward from the shaft 1. Each of these arms 25 has diverging hangers 26 piovotally connected to it and the lower ends of each pair of hangers are fixed to a runner 27 which extends between certain of the teeth of the harrow and below the harrow frame, and. has its forward end upturned, as The front end of the harrow frame is preferably connected to the tongue by means of links 29 or in any other desired manner so that aforward pull may be imparted to the harrow frame when the tongue 2 is pulled forward.

1t is obvious that when the shaft 1 is rocked by pulling backward on the lever 4 the arms 24 press rearwardly on rods 23 and arms 22 and force the teeth 20 downward into operative position. The arms 25 at the same time lift the runners 27 above the ground so that material is free to accumulate thereunder. The gears 12. will also rotate the gears 11 so as to swing the arms 13 forward and downward and thereby permit the harrow frame to besupported solely by the teeth 20. Vhen the machine is drawn forward these teeth will collect stalks, etc., in the path thereof and when it is desired to disengage them the lever 4 is pushed forward so as to cause the arms 25 to move downward and the arms 24 to move upward. As a result the runners 27 will be pressed downward on to the accummulated material, whereas Q evier? the teeth 20 will be quickly withdrawn from l for simultaneously lifting the frame toward engagement with said material.
